　　据了解，这种��-甘露聚糖酶由Thermothelomyces thermophilus DSM 33149产生。经过评估，专家小组无法就添加剂对目标物种和消费者的安全性得出结论，但被认为对环境是安全的。在建议的使用条件下该添加剂对育肥鸡具有潜在的有效性，并且该结论可以推广到育肥火鸡、育肥小型家禽物种和观赏鸟类。部分原文报道如下：

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of endo-1,4-��-d-mannanase produced by Thermothelomyces thermophilus DSM 33149 (Natupulse ?TS/TS L) as a zootechnical feed additive for chickens and turkeys for fattening, minor poultry species for fattening and ornamental birds. The additive under assessment, Natupulse ?TS/TS L, does not pose any safety co ncern regarding the production strain. The FEEDAP Panel co ncluded that the additive is tolerated by chickens for fattening, and this co nclusion can be extrapolated to all poultry for fattening. Due to the lack of reliable data regarding the potential of the additive to induce chromosomal damage, the FEEDAP Panel cannot co nclude on the safety of the additive for the target species and on the safety for consumer. The use of the additive in animal nutrition is co nsidered safe for the environment. The additive is co nsidered not to be irritant to the skin and eyes but is co nsidered a respiratory sensitiser, although exposure by inhalation is unlikely. The Panel could not co nclude on the potential of the additive to be a skin sensitiser. Due to the lack of reliable data, the FEEDAP Panel co nsidered that a potential of the additive to induce chromosomal damage in exposed unprotected users cannot be excluded. Consequently, exposure of users should be minimised. The Panel co ncluded that the additive Natupulse ?TS/TS L has the potential to be efficacious in chickens for fattening at the proposed co nditions of use and this co nclusion can be extrapolated to turkeys for fattening, minor poultry species for fattening and ornamental birds.
